Abstract

ESTRUTURA DE MÚLTIPLAS CAMADAS, LAMINADO, E, ARTIGO. A presente invenção refere-se a estruturas de múltiplas camadas, laminados e artigos formados a partir de tais estruturas. Em um aspecto, uma estrutura de múltiplas camadas compreende (a) um filme de polietileno de múltiplas camadas, em que uma camada externa do filme compreende uma blenda polimérica de pelo menos um polímero à base de etileno e de pelo menos um copolímero de etileno-ácido, em que a diferença entre o índice de fusão (I2) do copolímero de etileno-ácido e do polímero à base de etileno é menor que 18, e em que o teor de ácido da blenda polimérica é maior que 0,2%; e (b) uma camada de metal que compreende um metal depositado sobre a camada externa do filme de polietileno.MULTI-LAYER STRUCTURE, LAMINATE, AND ARTICLE. The present invention relates to multilayer structures, laminates and articles formed from such structures. In one aspect, a multilayer structure comprises (a) a multilayer polyethylene film, wherein an outer layer of the film comprises a polymeric blend of at least one ethylene-based polymer and at least one ethylene-copolymer. acid, where the difference between the melt index (I2) of the ethylene-acid copolymer and the ethylene-based polymer is less than 18, and where the acid content of the polymeric blend is greater than 0.2%; and (b) a metal layer comprising a metal deposited on the outer layer of the polyethylene film.
